Turn signal keeps blowing fuse

[Papa]

Not knowing how you connected all your lights, is it possible to unplug them and blow out the connectors with a little compressed air? It sounds like you are getting a short to ground. There could be a bit of water in one of the connectors. Once you blow them out, put a dab of dielectric grease on all the contacts.

Yeah the short to ground is confusing. There's no connector, my lights are 'hard wired' with soldered joints, and heat-shrink tubing, and flex tube over all that - and tie wraps everywhere to stop movement. I was kinda paranoid when initially putting it together to stop this kind of weirdness. I wanted very high reliability from the wiring.

But ultimately that's pretty hard of course, without a custom harness and MIL SPEC connectors. And my car is a pretty harsh environment - stiffly sprung, driven hard, and zero weather proofing

When I find it, we'll all understand it
